digital multimeter/#2000


The Model 2000 61/2-digit Multimeter is part of Keithley¡¯s family of high performance DMMs. The 2000 is a fast, accurate, and highly stable instrument that¡¯s as easy to operate as it is to afford. It combines broad measurement ranges with superior accuracy specifications ? DC voltage from 100nV to 1kV (with 0.002% 90-day basic accuracy) and DC ohms from 100µohm to 100Mohm (with 0.008% 90-day basic accuracy).

High Throughput
The 2000 offers exceptional measurement speed at any resolution. At 61/2 digits, it delivers 50 triggered rdgs/s over the IEEE-488 bus. At 41/2 digits, it can read up to 2000 rdgs/s into its internal 1024 reading buffer.

Creating a self-contained multi point measurement solution is as simple as plugging a scanner card into the option slot on the 2000¡¯s back panel. This approach eliminates the complexities of triggering, timing and processing issues and helps reduce test time significantly.

High Measurement Flexibility
The 2000 has 13 built-in measurement functions, including DCV, ACV, DCI, ACI, 2Wohm, 4Wohm, temperature, frequency, period, dB, dBm, continuity measurement, and diode testing.

The frequency counter function can make accurate signal measurements up to 300 kHz, eliminating the need for a separate counter.

High Compatibility
TestPoint¢â Instrument Driver Libraries and run-time programs are included with the 2000 to simplify IEEE-488.2 and RS-232 program generation. A variety of ready-to-run applications programs are also included. A LabVIEW library for the 2000 is available.

High Reliability
The 2000 conforms to rigorous standards governing safety and reliability, including UL-1244, CSA, IEC-1010, FCC and VDE. A 1000V input rating guards against accidental overloads, and the instrument recovers from overloads in milliseconds. It can accommodate 1500V from high-to-earth for added protection and increased reliability.
